Association of Pre-procedural High Sensitivity C-Reactive Protein with In-hospital Outcome of Patients Undergoing Percutaneous Coronary Intervention
Keywords:High sensitivity C-reactive protein(hsCRP), In-hospital outcome, percutaneous co-ronary intervention
AbstractEmerging evidence links an elevated baseline inflammatory status to adverse outcome among patients undergoing percutaneous coronary intervention (PCI). Baseline inflammation measured by high sensitivity C-reactive protein hsCRP may prove useful for identification of high risk patients requiring adjunctive therapies. This prospective study was carried out in the department of cardiology, National Institute of Cardiovascular Diseases, Dhaka, during October 2012 to September 2013.Two hundred consecutive patients with CSA and UA undergoing PCI were included in the study. Study patients were divided into two groups on the basis of hsCRP levels. In Group I hsCRP levels were elevated, that is ?3 mg/L and in Group II hsCRP levels were normal, that is < 3 mg/L, with 100 patients in each group. Fol-lowing the procedure in-hospital outcome of study patients were observed. Increased inci-dence (44%) of adverse in-hospital outcome was found in Group I (44% Vs. 11%). Higher incidence of post procedural angina (17%), peri-procedural myocardial infarction (6%) and peri-procedural myocardial injury (10%) was observed in this group. Nonsignificant rate of acute myocardial infarction, significant arrhythmia, acute LVF, cardiogenic shock and death were found in elevated hsCRP Group. Overall Major Adverse Cardiac Events (6% Vs. 0%) were found in pre-procedural elevated hsCRP group. High sensitivity C-reactive protein remained independently predictive of adverse in-hospital outcome, with 95% CI of RR 1.4 4.4 and p<001. The present study concludes that the hsCRP is an important and independent predictor of adverse in hospital outcome.
